The Gilded Bellbird (also known as Avian Chaos in the SNES/PS version) is an enemy in Chrono Trigger. First appearing in Guardia Forest during the Present, this creature appears as a bird with olive-green feathers, clenching a bell in its talons.

Gilded Bellbird appear early in the game and are usually used for leveling up before going to the Millennial Fair. Hiding within the trees, the birds emerge once the party comes closer to its hiding spot and squawk to alert Scarab in the area, who join Gilded Bellbird in battle.

Gilded means to be plated or overlain with gold, either for ornamentation or to reinforce an objects structure. Because Gilded Bellbird hold a bell made of a gold-colored metal, the name could allude to that. However, the second, less common meaning of gilded is "to give an attractive but often deceptive appearance to". Since Gilded Bellbird ring their bells to cause the Status Effect, Confuse, and to lure Scarab closer to the party, this interpretation seems more appropriate.
